How does an industrial water chiller work?
Dec 25 , 2023
An industrial water chiller is a device designed to remove heat from a process or equipment and transfer it to a separate water source. It is commonly used in various industrial applications, such as cooling machinery, lasers, plastic molding machines, and other processes that generate heat. The basic working principle involves the circulation of a coolant, typically water or a water-glycol mixtur...

How to chose a water chiller system for your stretch film machine and film blowing machine
May 10 , 2024
In the process of producing stretch film, the cooling system is very important, which directly affects the quality and output of stretch film. In general, we recommend choosing a chiller model with a cooling capacity slightly larger than the flow rate required for cooling, so as to ensure that the temperature and water flow rate can be kept within the required range under long-term stable operatio...

Working Principle and Advantages of Screw Chillers
Jun 24 , 2024
Like all chiller systems, a water cooled screw chiller consists of an evaporator, expansion valve, refrigerant, internal piping and controls. The main difference between screw chillers is their compressor. Screw chillers use two helical rotors to drive and compress the refrigerant gas. This type of chiller has nearly constant flow performance and is powered by an electric motor, steam or gas turbi...

What are the advantages of using glycol in chillers?
Jul 04 , 2024
Using glycol in chillers offers several advantages, including: Lower Freezing Point: Glycol mixtures have a much lower freezing point than water, which prevents the coolant from freezing in the chiller system, especially in low-temperature applications. This property makes glycol ideal for environments where temperatures can drop below the freezing point of water. Improved Heat Transfer Efficiency...
